Sonia Onion (Halifer) F1 is a mid-season hybrid of semi-sharp bulb onion developed by the Italian company Cora Seeds. The vegetative period is approximately 115-125 days, allowing this variety to be grown in open ground with the possibility of mechanized harvest collection. The plant is characterized by a well-developed root system and large dark green leaves, which facilitate its quick adaptation to various growing conditions.
Sonia bulbs have a round shape and medium or large size, with weights ranging from 150 to 250 grams. The outer scales have a rich bronze color, fit tightly to the bulb, and differ in hardness and dryness, ensuring reliable protection of the flesh from damage during harvest, transport, and storage. Thanks to these qualities, the onion is ideal for long-term storage and industrial processing.
The onion has a semi-sharp taste with a slight sweetness, making it a versatile product for culinary use. The hybrid is resistant to diseases such as Fusarium and downy mildew, which increases its reliability and yield. Sonia Onion F1 is the optimal choice for farmers seeking to obtain a high-quality commercial crop with good transportability and long-term storage indicators.
